Feature Details Page: Reasonably responsive details page

This MR contains a few styling changes to improve accessibility of information on the result listing and details page. There is a lot of work yet to do be done on these components (they need a major refactor when the data model for the UI is established). Thus, for now, a good enough job is done with the current implementation of the Result Item component to allow the user to access the available information on small screens.

Closes #117 (closed) #81 (closed)
